Ever will be 17 months tomorrow, and she sleeps in a queen-sized bed with her daddy and me. When she sleeps between us, she is covered, but when she sleeps on the other side of me (we have a bedrail there, to keep her from rolling out!) she throws off the blanket, so if it is cold, and I know she is going to be on that side, I put a sleeper on her. If she falls asleep in between us, I let her sleep in just a diaper. She seems to stay plenty warm that way, and we get lots of sleep! :-)
